Description
Technical field
The present invention relates to auto repair specific purpose tool field, specifically, be related to auto repair inductive heating head and by
The auto repair inductance heating device of the inductive heating head structure.
Background technology
In auto repair and industry processes, often need to carry out heat treated to some parts or workpiece, by electromagnetism
Sensing makes the heated method of object, is widely adopted because convenient and safe, promptly partly instead of traditional fire in recent years
Flame is heated, and electromagnetic induction heating necessarily an inductive heating head, also referred to as heating inductor, inductive heating head is a sense
Answer coil, or an induction coil with magnetic core.
Inductive heating head utilizes electromagnetic inductive heating principle, for sensing heating ironware during auto repair, during heating except
Heated ironware heating, inductive heating head itself can also produce heat, need cooled.
The mode of cooling inductive heating head is at present with two kinds：A kind of is natural cooling, has the disadvantage that speed is slow, cooling effect
Difference, arcing time factor are low --- and the i.e. continuous type time is short, and advantage is low cost or does not increase extra cost；Another kind of is water-cooled
Cooling, i.e., in the coil that copper pipe is constituted, water flowing is cooling down.Advantage is that speed is fast, and good cooling results, arcing time factor are high, have the disadvantage height
Cost, technology are more complicated, need Jing often to safeguard.
In structure, in the case of the power of inductive heating head is low power below 2 kilowatts, natural cooling is generally used
Method can meet requirement solving heat dissipation problem；In the case of power is powerful more than 6 kilowatts, generally with copper pipe it is logical come
Water cooling can also meet requirement；Situation of the power in 2-6 kilowatt of mid power, the structure of existing inductive heating head are typically
Sealant pouring and sealing or sealed with vinyl cover is close completely outside the induction coil.If cooled down with water-cooled, water-cooling system is complicated, relatively
For main frame, cost is too high, so often or using the method for natural cooling, the life-span for so heating head can shorten, make
The sealing often occurred with during outside induction coil is melted because overheated, the situation for causing inductive heating head to damage.
Notification number discloses a kind of coachbuilt body decoration correction electrical induction dress for the patent documentation of CN203289678U
Put.Which includes induction power supply transducer and heat induced device assembly；Induction power supply transducer is provided with induction apparatuss connection socket；Heating

Circle is powered and receives the signal that temperature sensor sends, and trachea is then connected to import 18, so that compressed air can be through shell
Heat is discharged from air vent 14 and air vent 17 respectively in space 19 between intracoelomic cavity and induction coil.
Half-shell 11 is symmetrical with regard to buckling surface with the internal structure of half-shell 12, by reflecting the figure of 12 internal structure of half-shell
9th, Figure 10, it can clearly be seen that air vent 14, air vent 17 are arranged on the faces different from import 18, are beneficial to flowing gas
Heat is discharged housing by body, and locator card 122 arranges 2, and the size of window 13 is can be preferred the end of horseshoe mouth tight circle.Handle
It is to be connected with housing by being arranged on the flange of its connection end, four screw holes is set on flange, shell is fastened on by screw
Handle is fastenedly connected by the mode of the screw 24 on body with housing.
Other embodiment of the auto repair with inductive heating head
In upper example air vent 14, air vent 17 from mould is simple and radiating reasonability from the point of view of arrange, certainly, if
Have during in view of left hand grip or right hand grip thermal current burn operator risk when, air vent can be set completely
Put on other faces in addition to the face of handle place of housing, such as when right-handed holds inductive heating head, can be in half-shell 12
Interarea on one group of air vent is set, the shape of air vent can also be circular or BAIYE shape.
For enabling the air-flow from import to air vent to take away more heats, can be with half-shell 11 and half-shell 12
One group of gusset for substantially complying with streamline is set on wall, can not only increase area of dissipation, moreover it is possible to improve the intensity of housing.
Induction coil is fixed on the mode of enclosure interior can also many obvious other modes.
If it is necessary, whole inductive heating head can be integrally manufactured with handle by housing, for example each half-shell is formed
There are the housing and grip portion of one depanning.
In upper example, housing is aluminum material, and handle is bakelite, it is clear that according to different design requirements, and both can be with
Using material of the same race.
The setting of temperature sensor 4 is mainly to provide inductive heating head temperature data signal, Ke Yixiang in real time to main frame
Upper example is equally arranged in inner walls, and advantage can be to avoid which from being subject to unsuitable collision.Can also be arranged on outside housing
On wall, such as in the seat of an indent on outer wall, advantage is easy for changing during maintenance.Coil 31 and magnetic core can also be arranged on
Between 32, advantage can be to obtain more accurate temperature data.
Auto repair inductance heating device embodiment
Referring to Figure 11, hinge structure, a gas access port on one side main frame 2, is increased, one end 31 of trachea 3 connects pressure
Contracting air source, the other end 32 connect gas access port, additionally, having the cable and gas of connection main frame 2 and inductive heating head in pipeline 5
Pipe, is additionally provided with a stop valve on one section of trachea inside main frame 2；On the other hand, main frame 2 need to be changed to control system
Enter, increase a control module, and be provided with temperature threshold, when the temperature data value that temperature sensor 4 is transmitted is more than temperature threshold
During value, control module controls the stop valve and opens, when the temperature data value that temperature sensor 4 is transmitted is less than temperature threshold, control
Molding block controls the stop valve and closes.
Auto repair inductance heating device other embodiment
According to the present invention, in other embodiments, 5 control module of temperature sensor can be saved, only need to be in the master of prior art
Arrange in the program of control circuit that inductive heating is first but electrified regulation, stop valve is opened simultaneously；Inductive heating head stops being powered and adds
After heat, stop valve time delay is closed for a period of time afterwards, so that inductive heating head is radiated to room temperature, is preferably avoided putting down inductance and is added
The situation for scalding people or object after hot head occurs.
